Why not make a show about people who go around modding and building things? They could take viewer requests to make things as “challenges” and there’d be a couple teams to allow 2-3 projects per episode. Thus if a project fails and is unusable there’s always a backup. Naturally the teams are assembled in such a way to create drama and arguments along the way.
Everything they build would then be auctioned off for worthy charities. So basically it’d be like American Chopper in that you see things being built, with a healthy dash of Mythbusters since everything is by viewer request. Then of course throw in deadlines to create a “ticking clock” a la Overhaulin’. It would also create a great community of people following the work and trying their own versions of it.
Of course I’m suggesting this here on my site because I would want to be involved. Maybe I’m off my rocker but I think it would be interesting – I’d certainly watch a show like that. Let me know what you think.
